CPA Redirector and WP 3.0?

Since WP 2.9 I just can't get it to work anymore.

I does redirect, but it shows the final site as the referer and not my site.

Tested with www.whatsmyreferrer.com
and multiple env checks.

Maybe downgrading is the only solution.

Any has this setup working?

EDIT: nvm, problem was the damn theme I was using.
